A pneumatic volume booster is a pressure regulation device that is controlled by a pilot pressure instead of a spring or adjustment thread as in an air pressure regulator. A volume booster may also be called a “pilot operated regulator”. The spring in a regulator normally supplies the mechanical pressure required to open the supply valve until there is an equal force balance between output pressure and spring force. In a volume booster, instead of a spring providing force balance, the “spring force” is supplied by a pilot pressure acting on a diaphragm. There are four basic air components to a volume booster circuit: supply pressure, regulated or downstream pressure, signal (pilot) pressure, and atmosphere (exhaust).
